Cultivated Straw Mushroom

1. Nutrient formula Dry straw 10 kg, rice bran 5 kg, dry cow dung powder 5-8 kg, vegetation ash 2 kg, lime 1 kg, calcium carbonate 1 kg.
2. For the nutrient composting, choose golden yellow (or green), foot dry, and mildew-free straw, chop the small piece of 1 to 2 cm, soak it in 1% lime water for 24 hours, remove and drain, build the heap, and pile it. 1.5 meters wide, 1.5 meters high, depending on the circumstances, generally not more than 1,000 kilometers is appropriate. Straw first shop 20 cm thick, and then sprinkled with cow dung (cow dung powder to be pre-mixed 2 to 3 days in advance), rice bran, calcium carbonate, grass ash, lime (lime dosage modulation PH to 7 ~ 8 is appropriate). This layer of straw a layer of accessories, until the heap is completed. After 3 days, it is turned over and the auxiliary materials are mixed with the straw when it is turned over. The briquettes can be made in two days.
3. The method for producing briquettes made several square wooden frames with a length of 40 cm and a height of 15 cm. Place the wooden frame on a flat surface and place a thin film on the wooden frame (about 1.5 meters long and 1.5 meters wide. A hole of 10 centimeters in diameter is drilled every 15 centimeters in the middle to facilitate water ventilation). The fermented culture material is loaded into the frame, compacted, the film is covered on the surface, the wooden frame is lifted, and a straw compact is formed.
4. Sterilization and Inoculation The preparation of grass blocks should be sterilized at normal pressure (8 to 10 hours at 100 degrees Celsius). After sterilization, they were moved into a cultivation room (beforehand, they were cleaned, 1,500 times more dichlorvos were used to kill insects, then formalin or sulfur powder was used for fumigation), and the waiting temperature was lowered below 37 degrees Celsius for inoculation. When inoculating, first open the film on the surface and sow with sowing method. Immediately after sowing, cover the film and put it on the mushroom bed to raise the bacteria.
5, Cultivation Management 5 days after inoculation, the surface of the film is unrolled, covered with 1 ~ 2 cm thick fire soil, and then 3 days will be able to spray water, keep the space humidity at 85% ~ 90%, two days Now the original base. This requires a certain amount of light and proper ventilation. The relative humidity of the mushroom house can be increased to 90% to 95% to promote the growth and development of the primordia. Generally 5 days after budding, mushrooms can be harvested. After the first tidal mushroom is harvested, the moisture content of the culture material must be checked, and lime water with a pH of 8 to 9 may be used to adjust if necessary. Then increase the temperature of the mushroom house to promote the growth of mycelium. Then manage according to the above method, until the end of cultivation, generally the entire cultivation cycle is 30 days, can pick 3 to 4 tide mushroom.
